Real Housewives' Kyle Richards Slams Brandi Glanville

She's appeared just once on Bravo's The Real Housewives of Beverly Hills and newcomer Brandi Glanville is already making waves.

For her second episode of the series -- airing Monday -- Eddie Cibrian's model ex, 38, hangs out with the Housewives at Adrienne Maloof's barbecue, and as the above preview clip shows, rubs Kyle Richards the wrong way.

"I just find her to be tacky," Richards snipes off-camera of Glanville, who called Richards' sister, Kim, a "slut pig" on the season preview trailer. "I don't like the words she uses and I'm not good at hiding it."
